Spire Glasgow
Owns spacecraft attitude and orbit control software and hardware across the full lifecycle, from R&D and design through manufacturing and on-orbit operations. Builds dynamics and control simulations including hardware-in-the-loop, designs and qualifies flight sensors and actuators, and works hands-on in lab and manufacturing environments. Interfaces with external contractors and internal teams in a fast design-to-launch cycle measured in weeks and months.
Spire Glasgow
Design, implement, test and maintain embedded firmware for satellite systems, working within a Platform team that interfaces with R&D, manufacturing and operations. Involves optimising serial protocols, debugging on-orbit and on-ground issues, and building interface tools, with FreeRTOS, Embedded C, Python/Bash and Arm Cortex microcontrollers in a fast design-to-launch cycle.
Astroscale Didcot
Develops and operates in-house flight dynamics software for orbital manoeuvres, rendezvous, docking and collision avoidance across multiple mission phases. Interfaces with GNC, ground segment and contractor teams, supports 24/7 shift operations, and works with MATLAB, C++ and Python in a hybrid Harwell-based team.
Astroscale Didcot
Designs and verifies the Guidance, Navigation and Control subsystem for on-orbit servicing missions, integrating GNC and computer vision algorithms with bespoke hardware for Rendezvous and Proximity Operations. The role spans requirements, FDIR, V&V strategy, trade-off analysis and flight software architecture, working alongside other engineering disciplines and external customers and suppliers.
Filtronic Cambridge
Designs, develops and integrates embedded software and firmware for advanced RF and communications products across the full lifecycle, from concept to volume manufacture. Strong focus on Zephyr-based development alongside embedded Linux, Yocto, bare-metal firmware, networking and secure communications, working closely with RF, FPGA, hardware and systems engineers.
Filtronic Cambridge
Lead the design, simulation and development of RF and mmWave circuits, components and subsystems, including system analysis, performance optimisation and troubleshooting. Carry out measurements, characterisation and validation of prototypes and production hardware, and support the transition from concept through prototyping into volume manufacturing. Works closely with electronics, mechanical, software and systems engineers, and contributes technical input to RFQs, proposals and customer engagements.
Gregory Martin International Chippenham £60,000 – £80,000 pa
Lead major consulting projects delivering systems engineering expertise to defence, energy and health clients, covering requirements, architecture, MBSE and V&V.

Gregory Martin International Portsmouth £60,000 – £80,000 pa
Lead major consulting projects across defence, energy and health, delivering requirements engineering, architecture development, MBSE and integration, verification and validation. Combines team leadership and mentoring with client delivery, bid input and business development, acting as a subject matter expert for UK MOD and defence primes.
Eutelsat OneWeb London
Designs and analyses the physical layer and air interface for next-generation satellite communications and the EU's IRIS2 system. Builds software simulators of user and feeder links (5G, DVB-S2X) to assess channel impairments, RF performance and system-level trade-offs, and sets technical requirements for vendors. Works within the System Engineering team, with a senior role mentoring a second engineer.
Eutelsat OneWeb London
Oversees the UK-based innovation team, managing ongoing partnership programmes with ESA, UKSA and other space agencies while identifying and structuring new collaborative initiatives. Coordinates contract changes, project reviews and stakeholder reporting, working with startups, engineering, finance and procurement across the UK and Europe.
Surrey Satellite Technology Guildford
Lead verification, testing and debugging of imager electronics for optical payloads, covering digital, analogue and mixed-signal circuits from concept through AIT, launch and commissioning. The role involves circuit-level debugging, board-level validation, test automation with Python or TCL, and designing ground support equipment within a collaborative optical payloads team.
NewOrbit Space Reading
Lead a team building the on-board flight-software stack for very low Earth orbit satellites, covering real-time control flows, autonomy, mode management and FDIR. You'll design and test deterministic C/C++ services on RTOS or Embedded Linux, integrate subsystems over I2C/SPI/CAN/SpaceWire, and take software from simulation through launch to on-orbit operations with over-the-air updates.
NewOrbit Space Reading
Structural analysis of flight hardware for VLEO satellites, covering static, modal, vibration, shock and quasi-static load cases. Builds and validates finite element models, performs hand calculations, and runs vibration and shock qualification test campaigns end-to-end, including instrumentation and model correlation. Works closely with mechanical, thermal, propulsion, systems and AIT teams across the full development lifecycle.
Holt Executive Oxfordshire £40,000 – £85,000 pa
Design, develop and validate flight dynamics software for defence and space missions, covering orbital mechanics, trajectory design and mission analysis. The role blends algorithm development in Python and MATLAB with requirements capture, verification and Agile Scrum delivery, acting as technical interface with suppliers and operations teams.
Copello Bristol £40,000 – £75,000 pa
Hands-on structural analysis role covering static strength analysis of metallic and composite aerospace structures across Defence, Security and Space. You will build and post-process FEA models in Nastran, ANSYS and Altair, analyse components and full-airframe load cases, produce stress reports and support structural testing, working with design, manufacturing, test teams, customers and suppliers.
